Paul here praises the brethren for their love for him, and thankful for how they constantly aided him. But now he is asking them to demonstrate that same love to brother Onesimus who is now saved, and helping him. This is a story of love and trust, and more importantly, forgiveness. When one has been forgiven they should be restored because of the love God to the person violated, as if it never happened. This is an example of the love and care for one another that God expects from us today; especially those that claim salvation.
